Health Insurance for Thailand Retirement Visas (O-A, O-X and LTR)

CoverFar is an independent information site, not an insurer or broker. Decisions on visas and residence permits belong to the authorities; the policy documents decide what is covered.

Thailand’s Non-Immigrant O-A, O-X and Long-Term Resident (LTR) routes have different health-evidence rules. Published instructions can differ and may include older provisions, so use your embassy’s current checklist and ask Thai immigration about extensions. The figures below are attributed to specific published sources, not a promise that a policy will be accepted.

Non-Immigrant O-A: the amounts

The Royal Thai Consulate-General in Chicago publishes the following O-A requirements for insurance covering the whole stay, including separate inpatient and outpatient amounts and an additional requirement effective from 1 October 2021:

• In-patient: at least THB 400,000 per policy year.
• Out-patient: at least THB 40,000 per policy year.
• Covid-19: Chicago states total cover of no less than THB 3,000,000 or USD 100,000 per policy year, including Covid-19.

The TGIA O-A guidelines describe first-year insurance from a Thai or overseas insurer with minimum coverage of USD 100,000, described as THB 3 million, including Covid-19 treatment. The portal labels the separate THB 400,000 / THB 40,000 renewal rule as applying before 1 September 2022. Do not treat that historical renewal label as a current extension rule. Confirm applicable amounts and forms with your mission, and ask immigration about extensions.

The insurance certificate you must attach

Chicago asks for a completed insurance certificate and original policy, accepting a policy copy for participating Thai insurers. It links the older foreign insurance certificate, with fields for outpatient and inpatient benefits. TGIA’s guidelines instead link a different foreign certificate with fields for Thailand territory and Covid-19 cover. Ask your embassy which form and signatures it currently requires; have the insurer complete its certification. A listed company or completed form does not guarantee acceptance.

O-X: a Thai-issued policy

Chicago’s O-X page lists Thai health insurance for the stay, with at least THB 40,000 outpatient and THB 400,000 inpatient cover. Its document checklist additionally states THB 3,000,000 or USD 100,000 total cover including Covid-19 per policy year. Check current eligibility, insurer and certificate rules with your own Thai mission before purchasing.

LTR: USD 50,000 or a deposit

For categories in the BOI LTR brochure, the health-evidence alternatives are:

• Health insurance with at least USD 50,000 coverage, or
• Social security benefits that insure treatment in Thailand, or
• A deposit of at least USD 100,000.

The BOI FAQ says to prepare health insurance or alternative documents meeting its criteria before applying. If insurance is unavailable at submission, an officer may request it during review. Ask BOI about your category, dependants, deposit conditions and required evidence.

Comparing the three visas

Checklist

1. Identify your exact category and the mission handling your application.
2. Ask which current amounts, policy period, form and signatures apply to your case.
3. For O-A, compare the policy dates, territory and benefits with the certificate; request corrections from the insurer.
4. For O-X, check the mission’s Thai-insurance and additional total-coverage requirements.
5. For LTR, ask BOI which insurance, social-security or deposit evidence it accepts for your category.
6. For an extension, ask immigration for current requirements rather than relying on the historical renewal section.

Prepare your policy evidence

Check that your name and passport number match your application and that the certificate identifies the insurer, policy number and exact coverage dates. Ask the insurer to state territorial scope and amounts in the form requested by your mission. If cover is expressed in another currency, ask the mission how it assesses it; do not assume a headline limit answers every requirement.

The two O-A forms are not automatically interchangeable. The older form has separate inpatient and outpatient fields; the other records a total sum insured including Covid-19 and refers to Thailand as a covered territory. A mission may also request the full policy. Compare the certificate with the policy schedule and ask the insurer to correct any mismatch before submission.

Check extensions separately

A visa application abroad and an application to extend a permitted stay in Thailand are separate procedures. The TGIA page explicitly dates one renewal section to before September 2022, so it should not be used as proof of a current extension threshold. Contact the immigration office handling your extension and ask which policy, duration and documentary proof apply to your visa history. Keep the policy and certificates accessible throughout your stay.

If another family member accompanies you, confirm that person’s visa category and its documentation requirements. A certificate naming only the principal applicant does not establish another person’s insurance. LTR dependants should ask BOI about their own evidence instead of assuming the principal applicant’s document is sufficient.

Insurance is not the whole application. The relevant mission may also ask for identity, financial, medical or other documents. Check its current instructions for the category you actually request, not a different retirement route. Where published sources differ or appear dated, ask the authority which checklist and certificate it uses now.

Questions before you submit

Ask your mission whether it requires an original policy, a copy, an insurer-issued certificate or a particular combination. Confirm the form version and the required signatories before sending it to the insurer. If the policy is issued overseas, ask how the mission wants the territory and benefits expressed, and whether it requires any supporting schedule or translation.

For an O-X application, ask the mission which Thai policies or certificates it recognises and how the additional total-coverage wording applies. For LTR, ask BOI what evidence satisfies the alternative you intend to use. If extending a stay, ask immigration directly; a consular visa checklist and the immigration extension procedure are not necessarily the same. Keep copies of your application documents and subsequent certificates for reference.

Before relying on any document, check whether it clearly identifies the person covered and the relevant policy or registration period. Keep both digital and paper copies where useful. If the evidence expires or your circumstances change before the appointment, ask the authority what updated documentation it needs. A certificate is evidence for the application, not a decision by the authority or a substitute for reading the underlying terms.
